how deep is vagina

The vagina is typically about 3 to 4 inches (7 to 10 centimeters) deep in an unaroused state. During sexual arousal, it can stretch and extend in length, reaching about 4 to 8 inches (10 to 20 centimeters) deep. This stretching ability helps accommodate different sizes and during intercourse or childbirth. The vaginal canal length varies among individuals, usually ranging between approximately 2.5 to 5 inches (6.5 to 12.5 centimeters), and it can expand significantly during arousal and other conditions.
